Before you call
Quick checks you can do safely
- Thermostat set to COOL and 3+ degrees below room temp
- Air filter — if it's gray and clogged, replace it and wait 30 min
- Outdoor condenser fan — is it spinning?
- Any ice visible on the line-set at the outdoor unit?
- Breaker: check both the indoor air handler and outdoor condenser breakers
What it usually is
Most common causes in St. Lucie West
- Dirty filter collapsed the evaporator coil into a block of ice
- Capacitor failed — outdoor fan or compressor won't start
- Low on refrigerant (usually a leak)
- Condenser coil packed with dirt, grass, pet hair
- Tripped float switch from a clogged condensate drain
When to stop troubleshooting and call: If the outdoor unit is silent and the breaker trips when you reset it, stop resetting it and call — that's an electrical fault.
